The purpose of this study is to verify the interceptal effect for microorganism within the expilium by the usual mask made pile gauze. Our experimental verification is as follows. (1) The experimentation for permentation of microorganism on piled thick gauze under the dry and wet situation. (2) The experimentation for passability of microorganism through piled gauze with the artificial quiet expiratory air flow under dry and wet situation which was sent out by our designed respiratory model. For the indicating microorganism was used Bc. Cerratia. On these result, the interceptibility of microorganism by piled gauze mask decreased along its humidity increased and microorganism passed to the outside gauze-face by quiet expirium in 1 hour.
